We have a 9 node cluster, 3 masters, 6 data. We've been using the java transport client, which connects to all 3 masters. Occassionaly the masters become unresponsive and needs to restart. Should the transport clients connect to the 6 data nodes directly instead? Thanks. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Depends, sounds like you need a few client nodes if you are OOMing your masters (which, is a bad thing to happen to masters).

We give the master nodes 5gb of memory -- stats are showing low cpu & memory utilization. Would you still recommend the client only node? If so, how many & powerful?

It depends on your use, but try adding one client in with 8GB heap and see how you go.

Would all transport clients only connect to this client node? Right now we have them connecting to all 3 master node.

Again, it's up to you. I'd suggest yes and let the masters manage the cluster. You may need more client nodes though.
